SUMMARY
The discussion centers on the feasibility of fabricating gallium nitride (GaN) quantum dots using chemical vapor deposition (CVD) techniques, specifically with nanoporous alumina or nanoporous silicon as substrates. The participants highlight that III-V quantum dots have been successfully produced using metal-organic chemical vapor deposition (MOCVD) for over a decade, utilizing a self-assembly method that involves depositing monolayers on a GaAs substrate under tensile strain. While the original poster seeks alternatives to molecular beam epitaxy (MBE), it is noted that the substrate growth typically requires MBE, although further exploration of MOCVD-only methods is suggested.
